If you're re-rigging your road bike shift cables and will have nothing less that Shimano's Dura-Ace level cables and housing, go with the Shimano SUS Road Shift Cable Set. It features SP41 housing, Shimano's stiffest and most responsive, and stainless cables which are highly stretch resistant and will last season over season. Treat your drivetrain right with some awesome cables.

These are normal cables and they do normal cable stuff. It's not a competitive market, they all do the exact same thing. The only comment I'd like to make is that if you're trying to run them internally, they don't provide enough housing to do both derailleurs (barely enough to do one)... these aren't the cheapest cables you can get so the fact that i have to go to the LBS and get some more housing just to finish the job is pretty annoying. Though I will say if the cables are externally routed or fenneled internal cables you'll be fine.
